Stack Overflow is currently engaged in the same kind of transformation. It's sad to see these giants of user participation turning away from what (I believe) made them so wonderful, and towards raw-numbers-growth at all cost. I suppose the folks with the money will be happy, but it diminishes our culture. The pursuit of quality content certainly supports sustainable growth, but it seems that it's just not big and fast enough [to pay the VC piper][0].
